摘　　要：为了提高以连续采煤机为核心的短壁机械化开采的施工工效,对开采工艺系统进行了优化。利用EML340型连续采煤机在神东大柳塔矿和乌兰木伦矿进行的双巷掘进和旺格维利采煤的工业性试验,采用现场观测的方法,研究和分析了其工艺过程,提出了开采工艺系统的优化设计,并分析了影响系统稳定性的支护设备。结果表明:在原系统的基础上增加1台梭车和1倍的联络巷道数量后的优化设计,可以使系统的掘进速度提高1倍左右,生产效率提高70%左右。优化后的工艺系统可以使掘进速度和生产效率得到较大的提高,有助于安全高效矿井的建设。In order to improve the work efficiency of the continuous miner as the key for the shortwall mechanized coal mining,the mining technique system was optimized.The EML340 continuous mine was applied to the industrial trial on the double gateway driving and the Wangeviry mining method in Shendong Daliuta Mine and Wulanmulun Mine.The site observation method was applied to study and analyze the technique process.The paper provided the optimized design of the mining technique system and analyzed the support equipment affected to the stability of the system.The results showed that based on the previous system,the optimized design with one set shuttle car added and one time connection gateway quantity added could improve the driving speed of the system by two times and could improve the production efficiency about 70%.The optimized technique system could highly improve the driving rate and the production efficiency and could be favorable to build a safety and high efficient mine.
